I suggest you search You-Tube. When searching for other Quality tools, etc. i cam across several 8D topics. Most are between 30-60 min so i believe you will find several that fit you need there.
Search for 8D, TOPS, Eight Discipline, 8-Discipline, problem solving, etc.
The will not have quizes, but you can add them using something like Survey Monkey to test what is important in each of the 8 steps.
I recently came across a superb free video thoroughly covering 8D and the main quality tools including 5 Why. The video is three hours long, so you'd have to break it into segments and make up quizzes. To check it out google "Trigo effective problem solving" They also offer 2 day sessions including at your workplace.
